# How USDC works: a guide for businesses
USDC is a dollar token that Circle issues and redeems one for one. Each one is a balance in a smart contract, so it moves in minutes and can't be reversed. It's regulated in the EU and backed mostly by a money market fund, but it's a claim on Circle, not a bank deposit, and Circle can freeze it.

## Key takeaways
1. USDC is a stablecoin that Circle issues and redeems one for one for US dollars. Each one is a balance in a smart contract on a public blockchain, not a coin and not a bank deposit.
2. Circle says USDC is backed 100% by cash and cash-equivalent assets, mostly a government money market fund managed by BlackRock, and publishes monthly attestation reports.
3. In the EU, USDC is an e-money token under MiCA. In October 2026 the EBA classified it as the first significant e-money token, which brings direct EBA supervision of its reserves.
4. Only Circle can create or burn USDC, blacklist an address or pause the contract. Anyone can send it, any day, and a confirmed payment can't be reversed.
5. Qualified businesses can mint and redeem through Circle Mint, which Circle says costs nothing extra. USDC pays holders no interest, so hold what you need and convert the rest.

## The short answer
USDC is a stablecoin: a token that Circle issues and promises to redeem one for one for US dollars. On each blockchain it runs on, a smart contract keeps a ledger of which address holds how much, and sending USDC changes two lines in that ledger. Circle holds reserves, mostly in a money market fund, and publishes monthly attestation reports on them.
For a business, that means USDC moves like a message, around the clock and in minutes, and it's easier to document for an auditor or a bank than most stablecoins. But it's still a claim on one company rather than a bank deposit, and that company can freeze it.
## The five layers of a USDC
Every USDC your company holds depends on five things. Scroll through them in order, from the token you see down to the reserves behind it.
## Follow one USDC payment
A customer pays your company 10,000 USDC for an invoice. Here's every hand the payment passes through, and what to check at each one.
## Getting USDC directly from Circle
Circle's developer documentation says qualified businesses can apply for a Circle Mint account to convert US dollars to and from USDC "at no additional cost". Below that level, companies buy and sell USDC through an exchange or a payments provider, which set their own prices.
Every on-chain transfer also carries a network fee, paid by whoever sends it; see [who pays gas fees on stablecoin payments](https://alignlabs.dev/guides/who-pays-gas-fees-on-stablecoin-payments).
## USDC vs USDT
| | USDC | USDT |
|---|---|---|
| Issuer | Circle | Tether |
| Status in the EU | E-money token under MiCA; classified as significant by the EBA in October 2026 | Not authorized under MiCA |
| Reserve reports | Monthly attestations | Quarterly attestations |
| Reserve assets | Mostly a government money market fund managed by BlackRock, plus cash at banks | Mostly Treasury bills and repos, plus precious metals, secured loans, bitcoin and equities |
| Direct redemption | Circle Mint, for qualified businesses | Verified customers, from $100,000 |
| In circulation | About $71.4 billion (2 November 2026) | About $183 billion (October 2026) |
| Who can freeze it | Circle | Tether |
USDT carries more payments, especially in emerging markets and on Tron; USDC is easier to document.

## Is USDC safe?
For paying and getting paid, USDC is one of the better-documented stablecoins, but it isn't as safe as money in a bank. In its favor, Circle says every USDC is backed by cash and cash-equivalent assets and publishes monthly attestation reports, and in October 2026 the EBA classified it as significant, which brings direct EU supervision of its reserves. In the US, the GENIUS Act requires issuers to back each stablecoin one for one with assets such as cash, short-term Treasury bills and government money market funds, from 18 January 2027; see [the GENIUS Act for non-US businesses](https://alignlabs.dev/guides/genius-act-for-non-us-businesses). Against it, USDC is a claim on one company, with no deposit insurance. Circle can freeze an address, a confirmed payment can't be reversed, and in March 2023 USDC briefly traded away from $1 when more than $3 billion of Circle's reserves were stuck at Silicon Valley Bank as it failed. So hold the USDC your upcoming payments need, and keep the rest as money in a bank account. The five risks below are the ones that cost businesses money in practice.
## Five risks, and how to manage them
| Risk | What can happen | What to do |
|---|---|---|
| Wrong network | Tokens arrive on a chain your wallet doesn't watch | Name the network on every invoice and ask for a small test payment. If it's already happened, see [sent USDC to the wrong network](https://alignlabs.dev/guides/sent-usdt-to-wrong-network) |
| Frozen funds | Circle blacklists an address, and its balance can't move | Know who pays you and record each sending address. See [why USDT and USDC get frozen](https://alignlabs.dev/guides/why-usdt-usdc-get-frozen) |
| Price away from $1 | In March 2023, Circle's transfers of more than $3 billion out of Silicon Valley Bank failed to settle before the bank went into receivership, and USDC temporarily traded away from its price | Don't hold more USDC than your upcoming payments need |
| Currency | If your costs are in euros or pounds, a dollar balance moves with the exchange rate | Convert to the currency you spend in planned amounts, or hold EURC for euro costs |
| Local rules | Rules for stablecoins and providers differ by country | Check the rules where you and your counterparties operate. See [stablecoin regulation by country](https://alignlabs.dev/guides/stablecoin-regulation-by-country) |
## How Align handles USDC
Align lets your company hold USDC, plus USDT and EURC, next to balances in USD, EUR, GBP and AED, in a [stablecoin business account](https://alignlabs.dev/accounts/stablecoin-business-account).
- **Deposits:** USDC on Ethereum, Solana, Base, Polygon, Arbitrum, Optimism or Avalanche, from a wallet or exchange account your company owns. Each network has its own deposit address.
- **Payments from customers:** if you want customers to pay you in USDC directly, [ask Align first](https://alignlabs.dev/contact), before you put an Align deposit address on an invoice.
- **Sending:** Align pays the network fee when you send USDC or USDT from your Align balance.
- **Paying out:** convert and pay suppliers and staff in USD, EUR, GBP or AED, or send USDC to wallets. Pricing is quoted on request.
Align isn't a bank, and your balances aren't bank deposits or covered by deposit insurance. Align is registered with FINTRAC in Canada as a money services business. It isn't authorized under MiCA, and this guide is not an offer of crypto-asset services in the EU.

## Common questions
### Is USDC the same as having dollars in the bank?
No. USDC is a claim on Circle, not on a bank, and it has no deposit insurance. Circle says it's backed 100% by cash and cash-equivalent assets and redeemable one for one for US dollars.
### Who backs USDC, and how do I check?
Circle holds the reserves, mostly in the Circle Reserve Fund, a government money market fund registered with the SEC and managed by BlackRock, plus cash at banks. It publishes monthly attestation reports by an accounting firm on its transparency page.
### Can my company redeem USDC with Circle directly?
Qualified businesses can apply for a Circle Mint account, which converts US dollars to and from USDC. Circle says this comes at no additional cost. Most companies convert through an exchange or a payments provider instead.
### Can Circle freeze USDC?
Yes. Circle can blacklist an address at the contract level, for example after a sanctions listing or a law enforcement request, and the USDC there can't move. A freeze applies to an address, not to tokens that have already left it.
### Does holding USDC earn interest?
No. Circle keeps the return on the reserves, and holders receive nothing. In the EU, MiCA's Article 50 bans issuers of e-money tokens, and crypto-asset service providers, from granting interest on them.
